대용량 병렬 양방향 컨버터를 이용한 배터리 충$\cdot$방전기 해석

An Analysis of Battery Charger$\cdot$Dischrger using Parallel Connected Bi-directional Converter

The battery charger of spacecraft has two different modes of operation respectively. One is the bus voltage regulation mode and the other is the charge current regulation mode. And also the battery discharger provide the power during eclipse mode of spacecraft. In this study, a test model of the battery charger and discharger using hi-directional converter are designed and analyzed. These Battery Charger and Discharger is introduced the modular converter method that can be added the converter modules according to the load variation.
